WirelessHD: High-speed wireless HD video streaming technology

The world's six leading consumer electronics manufacturers will work together to develop a wireless technology that can transmit high-resolution video images and erase the mess of wires connecting TVs and digital recorders and family sound system.

WirelessHD Consortium Alliance includes LG Electronics, Matsushia Electric, NEC, Samsung Electronics, Sony and Toshiba along with SiBEAM, a start-up enterprise specializing in wireless technology.

Seven companies announced that they would "free" high resolution TVs from the jumble of cables still used to connect satellite receivers, game consoles, DVD players and even portable camera cameras or devices. Other portable multimedia. This format is designed to cover up to 32 feet (6 meters) - but only inside a room.

However, according to analysts' estimates, the first batch of products equipped with WirelessHD technology will not be available before 2008.

Unlike current wireless formats, WirelessHD is backed by all major electronics companies, so it will have a huge advantage, said In-Stat analyst Brian O'Rourke. The video signal that WirelessHD transmits is not compressed so its quality compared to normal HD cable connection is exactly the same, said WirelessHD president.

There are many barriers

WirelessHD Consortium has been working quietly for more than a year now and intends to complete the specifications next fall. The group's intention is to integrate the technology into high-definition TVs and a range of future audio-visual devices, as well as adjust it to be compatible with other wired and wireless video formats.

If you buy old-fashioned DVD players or wired digital recorders, that's fine, because there will be a WirelessHD adapter that lets you wirelessly connect to the TV as usual.

However, to transmit HD video continuously, seamlessly and wirelessly requires a huge amount of radio bandwidth. That is not to mention many technical issues related to image quality and noise phenomenon.

Although it has not yet announced how WirelessHD works, the seven firms claim that the technology will deliver video signals at speeds up to many Gb - faster than any developing radio technology.

However, making the cost of this technology affordable for both manufacturers and consumers is a difficult problem. " WirelessHD says they aim for a cheap solution, but we have to wait and see, " expert O'Rourke shrugged.
